Canon EOS Rebel T4i Instruction Manual - Page 151

A Menu Function Settings Aspect ratioN The image's aspect ratio can be set to [3:2], [4:3], [16:9], or [1:1]. The area surrounding the Live View image is masked in black when the following aspect ratios are set: [4:3] [16:9] [1:1]. JPEG images will be saved with the set aspect ratio. RAW images will always be saved with the [3:2] aspect ratio. Since the aspect ratio information is appended to the RAW image, the image will be generated in the respective aspect ratio when you process the RAW image with the provided software. In the case of the [4:3], [16:9], and [1:1] aspect ratios, the aspect-ratio lines will appear during image playback, but the lines are not actually drawn on the image.

The image area displayed for the asterisked aspect ratio is slightly larger than the recorded area. Check the captured images on the LCD monitor when shooting. If you use a different camera to directly print images shot with this camera in the 1:1 aspect ratio, the images may not be correctly printed. 151
